GrouponPOSiPadAppAppearsInTheAppStore,ThenDisappears

Earlier today, a brand new app from Groupon called Groupon POS appeared in the App Store. The application, optimized for the iPad only, offered merchants a means of accepting and managing payments while on the go, from Apple's tablet computer. Since Groupon didn't provide an announcement or press release for Groupon POS, the application's launch came as a surprise. However, as of this writing, the app is no longer available to download in the App Store, signifying that Groupon POS was released prematurely.
As first reported by 9to5Mac:

The new Groupon POS app appears to be a scaled back version of the Breadcrumb POS app that the company acquired last year with the iTunes page noting that it best suited “for a wide variety of merchants from cafes and delis, to salons, spas, and florists.”
The iTunes page also says the app will work “with an optional cash drawer and printer,” although its unclear if Groupon plans to sell the hardware directly to customers like Square recently started doing with its business in a box offer.
